Prime Minister Justin Trudeau is expected to launch a federal election campaign this Sunday, with the vote set to be held as early as Sept. 20, sources have confirmed to CTV News. After months of speculation over the prospect of a pandemic election, sources, speaking on a not-for-attribution basis, said that Trudeau is planning to visit Rideau Hall this weekend and ask Gov. Gen. Mary Simon to dissolve the 43rd Parliament and draw up the 338 writs of election. However, sources indicated that it is still possible that the prime minister could adjust his plans. If the campaign kicks off this Sunday, with an election day on Sept. 20, the 2021 federal election would be 36 days in length, the shortest possible permitted under elections law. Triggering the election means that Canadians would be in for at least five weeks of campaigning, seeing the federal party leaders crisscrossing the country and pitching themselves, their candidates, and their platforms, under ongoing COVID-19 public health restrictions. While the next fixed election date isn’t until October 2023, minority governments rarely last the full four years between elections.
